SASH-CORD FASTENER.

To all whom it may concer/n.'

Be it known that l, CHARLES BONHAM, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented certain new and. useful Improvements inSash-Cord Fasteners; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates generally to builders hardware and particularlyto sash cord fasteners.

The invention has been designed in order to provide a sash cord fastenerwhich can be made very cheaply and economically, one which may beapplied very quickly and easily, and one having an improved means forgripping a sash cord.

The novelty in the invention, resides in the various details ofconstruction, and combination and arrangement of parts,

which are hereinafter fully described and 5 claimed, and shown in theaccompanying drawing.

In the accompanying drawing, forming a part of this specification Fig. lis an edge view of a sash equipped with a sash cord fastener constructedin accordance with the principles of the present invention;

Fig. 2 is a vertical sectional view of the sashand sash cord fastener;

Fig. 3 is a transverse sectional view taken substantially on the planeindicated by the line 3 3 of Figs. 1 and 2; and

Fig. 4L is a perspective view of the improved sash cord Jfastener,illustrating a sash cord gripped thereby.

In the illustrated embodiment of the invention, the sash cord fasteneris shown as comprising a metal strip or bar 1 having it-s upper end bentat right angles to provide an attaching ear 2. The ear 2 is apertured asat 3. The lower end portion of the strip or bar l is widened to providewings 4 which are designed to be rolled or curved Vtransversely so as toform a conical shape socket 5. Apertures 6 are pierced through edge.

the wings 4 so as to form comparatively sharp inwardly extending spurs 7on the inside of the socket 5.

The fastener as it is placed upon the market does not have the socket 5completely formed, but the free edges of the wings 4 are suiiicientlyspaced apart to permit the end of a sash cord C to be inserted inthesocket, and when that has been done, the wings 4 may be hammered orotherwise forced together so as to completely form the socket 5 andcause the sash cord C to be gripped by the spurs 7.

To adapt a sash such as shown in the drawing and represented by theletter S to receive a sash cord fastener constructed as described in theforegoing, it must have a groove N formed in the upper` end portion ofits side It is also preferable to have a recess R formed in the sash Sas an extension of thegroove N. The point or lower end of the socket 5should be inserted in the recess R and the remaining portion of thefastener should be placed in the groove N with the back of the strip orbar 1 resting flat against the bottom of the groove N. The ear 2 willthen extend over the upper edge of the sash S and a screw 8 may be eX-tended through the aperture 3 in the ear 2 to secure the fastener inplace. When in place in the grove N, the sash cord C will also bedisposed entirely within the latter.

From the foregoing description taken in connection with -theaccompanying drawing, the construction, use and advantages of theinvention will be readily understood without further explanation.

It is obvious that various changes in form, proportion, and in thevarious details of construction may be made without departing from theprinciple or sacrificing any of the advantages of the invention, andhence it is to be understood that such changes may be made within themeaning and scope of the appended claim which defines the novelty of theinvention What is claimed is:

`A sash cord fastener comprising a relatively narrow strip of pliablemetal having its upper end apertured and bent laterally to form anattaching ear, said strip being widened et its lower end to provide apair of wings, Said wings being relatively wide at their tops andgradually decreasing in width 5 toward Vtheir lower ends and beingadapted to be rolled toward each other to form a substantially conicalsocket for reception of one end of the cord, said wings being:r providedwith indentations forming spurs on the interior of the socket forembedding` in the fibres of Jthe oord. Y

In testimony whereof I have hereunto affixed my Signature.

CHARLES BONHAM.
